Message-ID: <20090115110644.377ebc38@lithium.local.net> Date: Thu, 15 Jan 2009 11:06:44 +0000 From: Alex Buell <alex.buell@...ted.org.uk> To: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: 2.6.27, ext4 and bad USB disks I've got a couple of bad disks here which I just tested with ext4 over USB 2.0.
